@666shellshock if your trying to get better at playing and singing you might not want to jump into Metallica just yet.The song I’ve been using is Polly by Nirvana,very rythmic and easy to sing.What’s more is that Metallica songs tend to be at least five minutes,so picking a shorter song can also help.I don’t intend to argue or offend its just an opinion from one musician to another think nothing of it.
